General Description

This is a single R~80000 observation of T Cha in one setting in the M
 band (12/1/n and 12/1/i)

The main target is T Cha (11 57 13.5 -79 21 32).
The spectroscopic standard is HR 4679 (12 18 26.3 -64 00 11.1).

It is important to observe the standard and science target with similar airmass.
 However,
the target is pretty far south, so it might not be possible to do better than 0.2-0.3
 airmasses. We'll be happy with the best you can do.

Both science and standard are bright targets with (M=5.5, and M=4.0, resp.) and
 both have V-M~0, so should be easy to identify in the slit viewer camera.

Do the README file and the instrument comments of the telluric stars OBs include the required S/N/pixel of the spectrum of the telluric star, its spectral type and allowed spectral range?

Do any OBs include wavelength or flatfield calibrations?

If you are observing Moving Targets, have you attached suitable ephemeris files to your OBs?

N/A
```

If the slit viewer guide star is different from the target, are the RA and DEC offsets accurate to within 0.05 arcsec and do they take into account the relative proper motion between the two objects?

```
N/A
```

If you have preferences which OBs should be executed first for objects at similar RA, did you make use of the User Priority field in the OBs?
